question was like this "A patient was hit on neck and some bone chip entered into the spinal cord from lateral side. which of the following would be affected first: Ipsilateral proprioception of arm ipsilateral proprioception of leg ipsilateral proprioception of thigh region Contralateral proprioception of upper limb " Ans: A
In the dorsal column of cervical spinal cord there is fasiculus cuneatus (towards outer side ) and fasiculus gracilis ( towards inner side).. F. Cuneatus carries proprioception from upper limb and F gracilis from lower limb....So the answer is simple..in case of neck injury from lateral aspect, it's the ipsilateral proprioception of upper limb that will be gone.
Sir in MCQ 6 , image was same but options were totally different. Point E was marked at the black point just behind where it is marked now 1) Point B to D is Absolutely refractory period 2) Point E start of increase in threshold or something Increase of was mentioned , if u could say what it means of increase. 3) Point D is due to closure of Na channels and opening of slow K channels. 4) Point B Related to something about K channels.
@@aditya10oct97 I think they didn’t mention “only calcium channel opens in phase 2” as far as I remember they just simply said calcium channels open in phase 2. Which is not a wrong statement
@@siddheshmohite800 i agree bro statement 2 is correct coz na k atpase isn't specific to ventricular myocyte anyhow, anyways how much correct are u getting
Sir in MCQ no 3 they asked rmp increase in one option and in another option they said rmp increase and later decreases sir..what could be the answer sir??

Thank you sir!
MCQ 4 : Sensory modalities from Upper and Lower limb were given as options
question was like this "A patient was hit on neck and some bone chip entered into the spinal cord from lateral side. which of the following would be affected first:
Ipsilateral proprioception of arm
ipsilateral proprioception of leg
ipsilateral proprioception of thigh region
Contralateral proprioception of upper limb
" Ans: A
In the dorsal column of cervical spinal cord there is fasiculus cuneatus (towards outer side ) and fasiculus gracilis ( towards inner side).. F. Cuneatus carries proprioception from upper limb and F gracilis from lower limb....So the answer is simple..in case of neck injury from lateral aspect, it's the ipsilateral proprioception of upper limb that will be gone.
Ok. So that was the actual question. Great 👍
Some student told, question was hemi-section!
It was.." a patient was hit on neck and some bone chip entered spinal cord laterally...what is most likely to be lost..
Ok. Thanks for the actual recall !
Ipsilat proprioceptors of upper limb will be best choice then.

4) Point B Related to something about K channels.
Noted dear. Thank you
@@drmanna sir aap iska answer bata sakte ho bcoz maine Point E se related mark kiya tha.
B to D will be the answer
Thank you sir
Point B to D is refractory period is given in options and that is correct answer
Yes! Correct !
In mcq 7 answer was FRC sir confirmed.
Yes audible sir
Sir graph was from zero level but below to ERV so RV should be the ans.
Yes
Sir in 6th questions u option was refractory period not absolute refractory period and point b threshold not point a threshold
Ok. Thank you 😊
I guess the correct answer is refractory period.
@@jyotiradityasingh1878 yes
In Q1, one of the options was endocytosis
Q.2 Second type graph was given
Phase 4 is due to NKatpase is this correct ,,,, this option was there sir
Not fully correct! It’s mainly due to K+
@@drmanna sir but phase 2 is also not due to calcium only it also involves k channels
@@drmanna sir in phase 4 rmp is attained( rmp of k+ is its equlibrium potential)then how sir k+ion contribute in phase 4 ....

Noted dear !

Please reply this was the actual option
Que 6 option are not correct
Yeah! Many students are saying so. Probably B to D Refractory period was an option, which is correct !
Yes sir that was the exact option! Thank you
6.50 was the graph
Ok
Sir option was
Point B is threshold potential.
Another was point B to D is absolute refractory period
Proprioception
